5. Operating Instructions
Once installed and filled with the correct gear oil, the hub caps operate passively, protecting your wheel bearings. Regularly check the oil level through the transparent window to ensure adequate lubrication. The oil level should be maintained between the 'FULL' and 'ADD' markings.
6. Maintenance
- Regular Inspection: Periodically inspect the hub caps for any signs of damage, cracks, or leaks. Check the transparent window for clarity and ensure the oil level is correct.
- Oil Level Check: Use the transparent window to monitor the gear oil level. If the level is low, add the recommended type and amount of gear oil through the fill port.
- Gasket Integrity: Ensure the gaskets are in good condition. Replace them if they show signs of wear or damage to maintain a leak-proof seal.
- Cleaning: Keep the exterior of the hub caps clean to easily spot any potential issues and maintain the visibility of the oil level window.
7. Troubleshooting
- Oil Leakage: If you observe oil leakage, first check the tightness of the mounting bolts. Ensure they are torqued evenly. Inspect the gasket for proper seating and damage. Replace the gasket if necessary.
- Cloudy Window: A cloudy transparent window might indicate internal contamination or degradation of the plastic. While it may not affect function immediately, consider replacement for better oil level visibility.
- Loose Fit: If the hub cap feels loose after installation, re-check the bolt torque. Ensure the mounting surface is flat and clean.
